2.2 Establishing Communication with the PDS 210
Connecting Your Computer to the PDS 210 for PPI Communications
Figure 2-1 shows a typical configuration for connecting your personal computer to your
PDS 210 with the PC/PPI cable. To establish proper communications between the
components, follow these steps:
1. Set the dipswitches on the PC/PPI cable for the baud rate of 9600 baud.
2. Connect the RS-232 end of the PC/PPI cable labeled PC to the communications port of
your computer, either COM1 or COM2, and tighten the connecting screws.
3. Connect the other end (RS-485) of the PC/PPI cable to the communications port of the
PDS 210, and tighten the connecting screws.
